doc: Move "About" content from index.rst to a new chapter

The index.rst page is now the primary landing page for the TF-A
documentation. It contains quite a lot of content these days,
including:

- The project purpose and general intro
- A list of functionality
- A list of planned functionality
- A list of supported platforms
- "Getting started" links to other documents
- Contact information for raising issues

This patch creates an "About" chapter in the table
of contents and moves some content there. In order,
the above listed content:

- Stayed where it is. This is the right place for it.
- Moved to About->Features
- Moved to About->Features (in subsection)
- Stayed where it is. Moved in a later patch.
- Was expanded in-place
- Moved to About->Contact

-Release Processes
-=================
-
-Project Release Cadence
------------------------
-
-The project currently aims to do a release once every 6 months which will be
-tagged on the master branch. There will be a code freeze (stop merging
-non-essential PRs) up to 4 weeks prior to the target release date. The release
-candidates will start appearing after this and only bug fixes or updates
-required for the release will be merged. The maintainers are free to use their
-judgement on what PRs are essential for the release. A release branch may be
-created after code freeze if there are significant PRs that need merging onto
-the integration branch during the merge window.
-
-The release testing will be performed on release candidates and depending on
-issues found, additional release candidates may be created to fix the issues.
